Public bug reported:
I was asked to report this bug here as I had originally reported it to the
Ubuntu Community Discourse:
https://discourse.ubuntu.com/t/latest-hwe-kernel-breaks-virtualbox-in-noble/64578
Ubuntu Version:
24.04.2LTS
Desktop Environment (if applicable):
Unity and GNOME
Problem Description:
After upgrading the kernel to the latest HWE kernel (6.14.0-24-generic)
Virtualbox fails to launch any VMs. Solution was to blacklist kvm, kvm-amd (on
my desktop GNOME system) or kvm-intel (on my laptop Unity system) and then
reboot
Relevant System Information:
Both desktop and laptop systems are completely up to date with maintenance.
What I’ve Tried:
Did some searches on the error messages produced by Virtualbox 7.1.10r169112
and discovered the solution which was to create
/etc/modprobe.d/blacklist-kvm.conf with the following entries:
blacklist kvm
blacklist kvm_intel # or kvm_amd
and then reboot.
